Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

Pin 1 End
Refer to page 4-13 for the procedure for servic-
ing the pressure switch.
1.
Unplug washer or disconnect power.
COMPONENT TESTING
Electrical Shock Hazard
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
• Unless stated otherwise, make all resis-
tance checks by disconnecting the compo-
nent connector at the Central Control Unit
(CCU).
WARNING
2.
Disconnect the hose and wire connector
from the pressure switch.
3.
Set the ohmmeter to the R X 1 scale.
4.
Touch the ohmmeter test leads to the
pressure switch connector pins shown
below. The meter should indicate 0 Ω for
each measurement.
